However, a specific IgM and IgGt production was observed before challenge in all the surviving pigs, irrespective of the type of immunization received. This antibody response was even greater after H. parasuis infection, especially in those survivors receiving the sublethal

dose. These results suggest a role of the antibodies developed after the different immunization protocols in preventing infection and death; therefore, the humoral immunity is protective against experimental Glasser’s disease. (c) 2008 Elsevier Ltd. All rights reserved.”
“LH and FSH have complementary functions in ensuring optimal oocyte maturation and ovulation. In women undergoing assisted reproduction technology protocols with gonadotrophin-releasing hormone analogues, LH and FSH concentrations are reduced. While FSH use in assisted reproduction technology is well established, there is no published consensus on the need for exogenous LH in

Asian patients. Having reviewed the concept of the LH therapeutic window and differences between recombinant human LH (r-HLH) and human menopausal gonadotrophin, a consensus was reached on which patient subgroups may benefit from LH supplementation. Adjuvant r-HLH gives clinicians precise control over the dose of LH bioactivity administered to target the therapeutic window. The use of r-HLH is recommended in women with poor response in a see more previous cycle or suboptimal follicular progression in a current cycle by day 6-8 of stimulation. r-HLH should also be considered in women at risk

of suboptimal response, LH and anti-Mullerian hormone concentrations, antral follicle count and LH polymorphisms require further research and verification. For measurement of LH response adequacy, the monitoring of follicular progression, oestradiol concentrations and endometrial thickness is recommended.

“Intelectins (Itlns) are lectins with potential roles in innate immunity, capable of binding bacteria via galactofuranose residues. Itlns also function as intestinal receptors for the antimicrobial glycoprotein lactoferrin (Lf). Since Lf binds strongly to enterohemorrhagic Escherichia coli O157:H7 (EHEC), we aimed to determine the expression of Lf receptor in terminal rectum, the site of predilection of EHEC in cattle. We sequenced two bovine intelectins (Itln1 and Itln2) and showed that both were expressed in abomasum and rectum, but expression appeared minimal in the jejunum. There was significantly higher expression of Itln2 in terminal rather than proximal rectum. Lactoferrin was expressed in all samples examined. Thus, we have demonstrated two novel bovine Itlns and shown that they are expressed along with Lf in the gastrointestinal tract, where they may interact with microbial pathogens.
